Pick up the phone and call Midwest Specialties.....They have not updated that website page....I had the same questions as you...I called them to get their advice on the plugs they sell and what SDR # they were designed for....They are very nice, and she answered all my concerns....they confirmed what most of the pyro's in the industry were using and let me know exactly which HDPE pipe to buy.....If I was at my normal computer I would post it...

I had a list of the HDPE sizes from my local Pro diusplay Co and what they use, but I must have lost it in my PC crash a few months ago.

There is some variation from company to company, and it could be due to shell mfg they preffer to use. Same as Excals are bigger than black box, but both are 1.75" shell...... I know some of the tubes were DR21 as well as the 17 listed

I'm looking for hdpe or fiberglass mortars for 1.5" shells (not 1.75"). Does anybody have them for sale? Are there any 1.5" shell kits that come with hdpe or fiberglass mortars?

I think someone sells mortars for 1.5" shells in AFN. I'm at work and my AFN news letters are at home. Can anyone else help now, or I'll take a look when I get home.
